  摘要：

  描述了通过Bischler-Napieralski环化合成一系列取代的1-苄基-3,4-二氢异喹啉。竞争性的亚甲基蓝敏化光氧合实验可确定1-苄基-3,4-二氢异喹啉的光氧合相对速率，已证明取代基会影响互变异构烯胺的平衡浓度和总光氧合速率。在校正了烯胺浓度的差异之后，相对速率数据提供了反应机理的诊断探针，该机理涉及限速步骤中电荷的转移。

• Enhancement of the carbamate activation rate enabled syntheses of tetracyclic benzolactams: 8-oxoberbines and their 5- and 7-membered C-ring homologues
  作者：Hiroaki Kurouchi

  DOI：10.1039/d0ob02096f

  日期：——

  A route to the direct amidation of aromatic-ring-tethered N-carbamoyl tetrahydroisoquinoline substrates was developed. This route enabled general access to 8-oxoberberines and their 5- and 7- membered C-ring homologues. It overcomes the undesired tandem side-reactions that result in the destruction of the isoquinoline backbone, which inevitably occurred under our previously reported superacidic carbamate

• Formation of carboxamides by direct condensation of carboxylic acids and amines in alcohols using a new alcohol- and water-soluble condensing agent: DMT-MM
  作者：Munetaka Kunishima、Chiho Kawachi、Kazuhito Hioki、Keiji Terao、Shohei Tani

  DOI：10.1016/s0040-4020(00)01137-6

  日期：2001.2

  Selective formation of carboxamides in an alcohol or water by an exceptionally convenient one-step procedure in which a condensing agent is simply added to a mixture of acids and amines has been achieved successfully by using a new condensing agent, 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMT-MM). Activation of carboxylic acids by DMT-MM in the presence of amines and subsequent aminolysis of the resulting acyloxytriazine in alcoholic solvents occurred selectively and led to the formation of carboxamides in excellent yields. The rate of aminolysis of the acyloxytriazine intermediate can be estimated to be about 2x10(4) times greater than that of methanolysis. The amide/ester selectivity observed using DMT-MM was much larger than that obtained with DCC or EDC. Condensation of polar substrates, such as amino acid esters and their hydrochlorides, glucosamine hydrochloride, sodium acetate and dicarboxylic acids, proceeded successfully in MeOH, water or aqueous MeOH in good yields. The present reaction is technically quite simple and easy to achieve. It proceeds by simple mixing of acids, amines and DMT-MM without any additives, and the MeOH is readily removable by a rotary evaporator after completion of the reaction.
